Resetting Components You can reset the active CMC, or to virtually reset servers making them to behave as if they were removed and reinserted. If the chassis has a standby CMC, resetting the active CMC causes a failover and the standby CMC becomes active. NOTE: To reset components, you must have Debug Command Administrator privilege. To reset the components using the CMC Web interface, 1. In the left pane, click Chassis Overview → Troubleshooting → Reset Components. The Reset Components page is displayed. 2. To reset the active CMC, in the CMC Status section, click Reset/Failover CMC. If a standby CMC is present and a chassis is fully redundant, a failover occurs causing the standby CMC to become active. However, if a standby CMC is not present, the CMC that is available is rebooted. 3. To virtually reseat the server, in the Virtual Reseat Server section, select servers to reseat, and then click Apply Selections. For more information, see the Online Help. This operation causes the servers to behave as if they were removed and reinserted. Saving or Restoring Chassis Configuration This is a licensed feature. To save or restore a backup of the Chassis configuration using the CMC Web interface: 1. In the left pane, click Chassis Overview → Setup → Chassis Backup. The Chassis Backup page is displayed. To save the chassis configuration, click Save. Override the default file path (optional) and click OK to save the file. The default backup file name contains the service tag of the chassis. This backup file can be used later to restore the settings and certificates for this chassis only. 2. To restore the chassis configuration, in the "Restore" section, click Browse, specify the backup file, and then click Restore. NOTE: CMC does not reset upon restoring configuration, however CMC services may take some time to effectively impose any changed or new configuration. After successful completion, all current sessions are closed. Troubleshooting Network Time Protocol (NTP) Errors After configuring CMC to synchronize the clock with a remote time server over the network, it may take 2-3 minutes before a change in the date and time occurs. If after this time there is still no change, it may be necessary to troubleshoot a problem. CMC may not be able to synchronize the clock for the following reasons: • Problem with the NTP Server 1, NTP Server 2, and NTP Server 3 settings. • Invalid host name or IP address may have been accidentally entered. • Network connectivity problem that prevents CMC from communicating with any of the configured NTP servers. • DNS problem, preventing any of the NTP server host names from being resolved. To troubleshoot the NTP-related problems, check the information in the CMC trace log. This log contains an error message for NTP related failures. If CMC is not able to synchronize with any of the configured remote NTP servers, then CMC time is synchronized to the local system clock and the trace log contains an entry similar to the following: Jan 8 20:02:40 cmc ntpd[1423]: synchronized to LOCAL(0), stratum 10 174

Resetting Components
You can reset the active CMC, or to virtually reset servers making them to behave as if they were removed and
reinserted. If the chassis has a standby CMC, resetting the active CMC causes a failover and the standby CMC becomes
active.
NOTE:
To reset components, you must have
Debug Command Administrator
privilege.
To reset the components using the CMC Web interface,
1.
In the left pane, click
Chassis Overview
→
Troubleshooting
→
Reset Components
.
The
Reset Components
page is displayed.
2.
To reset the active CMC, in the
CMC Status
section, click
Reset/Failover CMC
. If a standby CMC is present and a
chassis is fully redundant, a failover occurs causing the standby CMC to become active. However, if a standby
CMC is not present, the CMC that is available is rebooted.
3.
To virtually reseat the server, in the
Virtual Reseat Server
section, select servers to reseat, and then click
Apply
Selections
.
For more information, see the
Online Help
.
This operation causes the servers to behave as if they were removed and reinserted.
Saving or Restoring Chassis Configuration
This is a licensed feature. To save or restore a backup of the Chassis configuration using the CMC Web interface:
1.
In the left pane, click
Chassis Overview
→
Setup
→
Chassis Backup
. The
Chassis Backup
page is displayed. To
save the chassis configuration, click
Save
. Override the default file path (optional) and click
OK
to save the file. The
default backup file name contains the service tag of the chassis. This backup file can be used later to restore the
settings and certificates for this chassis only.
2.
To restore the chassis configuration, in the ”Restore" section, click
Browse
, specify the backup file, and then click
Restore
.
NOTE:
CMC does not reset upon restoring configuration, however CMC services may take some time to
effectively impose any changed or new configuration. After successful completion, all current sessions are
closed.
Troubleshooting Network Time Protocol (NTP) Errors
After configuring CMC to synchronize the clock with a remote time server over the network, it may take 2-3 minutes
before a change in the date and time occurs. If after this time there is still no change, it may be necessary to
troubleshoot a problem. CMC may not be able to synchronize the clock for the following reasons:
•
Problem with the NTP Server 1, NTP Server 2, and NTP Server 3 settings.
•
Invalid host name or IP address may have been accidentally entered.
•
Network connectivity problem that prevents CMC from communicating with any of the configured NTP servers.
•
DNS problem, preventing any of the NTP server host names from being resolved.
To troubleshoot the NTP–related problems, check the information in the CMC trace log. This log contains an error
message for NTP related failures. If CMC is not able to synchronize with any of the configured remote NTP servers, then
CMC time is synchronized to the local system clock and the trace log contains an entry similar to the following:
Jan 8 20:02:40 cmc ntpd[1423]: synchronized to LOCAL(0), stratum 10
